Australia’s Composting Crisis: Misleading Labels and Plastic Contamination in Organic Waste
Plastic Contamination in Composting
Experts warn about significant plastic contamination in food and garden waste due to user errors and misleading “biodegradable” labels. Major waste companies in Australia are urging the government to standardize the certification of compostable products. Many items labeled as “compostable” or “biodegradable” do not decompose as intended.
Government Initiatives
Australian states are launching food and organic waste collection programs to cut food waste in landfills by half by 2030. In New South Wales, councils must collect food and garden waste from all households by 2030.
Issues with Composting
Richard Kirkman, CEO of Veolia ANZ, highlights that plastic contamination in FOGO (food organics and garden organics) bins is a major issue. Many “compostable” items do not break down correctly, leading to low-quality compost. Proper composting requires that compostable products disintegrate within 12 weeks and fully biodegrade within six months in specific facilities.
Misleading Labels
Consumers often misunderstand product labels. “Biodegradable” items can take years to break down, whereas “compostable” items should decompose in a set time frame. Kirkman points out that some liners remain intact after 16 weeks of composting, complicating waste management efforts.
Research Findings
A Veolia study reveals that 72% of people mistakenly think single-use coffee cups labeled as compostable can go into recycling bins, while 58% incorrectly believe biodegradable plastic bags can be recycled. These items should be placed in landfill instead.
Call for Regulation
Experts advocate for clearer labeling and certification. Ash Turner from Cleanaway suggests the Environment Protection Agency (EPA) create distinct regulations for compostable items to help consumers choose correctly and assist waste processors in identifying non-compostable products.
Reassessing Bin Liners
Gayle Sloan, CEO of Waste Management Resource Recovery Australia, proposes eliminating bin liners altogether. She believes this would reduce confusion for consumers and decrease waste production.
By addressing plastic contamination and improving product labeling, Australia can enhance its composting systems and reduce landfill waste. Responsible consumer choices play a crucial role in this process.
